The main objects of this 4invention are First, to provide a bolt locking means 'for *bolt laction 'guns in Whiclitheiiight of the firing p i-ii is away from, and unim'peded' by the locking means. Second, to provide a breech bolt locking means which is autoinaticifn its operation. f Third, to provide anauto'matic breech bolt locl'ring means Which is'capable of manual release. 1 'liourth7 to provide abreech bolt locking,r means in which the parts are comparatively simple and are so forlilned and supported "that they are not likely to be injured or rendered inoperative infuse by severe'o'r careless Ymani'pi'ilationofthe gun i `Objects relating -to-'details' and economies of veonstri'iction and operation of my, invention will definitely appear from the detailed ydescriptionl to follow.
